Technical Description
(1) The DRP series regulators offer high resolution and repeatability. The lever mechanism magnifies the resolution of the high-precision fine adjustment thread to achieve minimal axial displacement. This unique design ensures uniform and smooth movement, which is largely independent of load.
(2) Two knobs are provided for coarse and fine adjustment respectively. The coarse adjustment provides an accuracy of 0.5mm per revolution within the stroke range, while the fine adjustment has a stroke of 300µm with a nominal 50µm per revolution. The modular brass adapter can be connected to mounting holes with Ø9.5mm, M9.50.5 or M141.0 specifications.
